Yesterday I got BoI HC and the week before it I got a WF cleave trinket from Malkorok. Of course, I was excited to have such amazing new gear (mostly the latter, haha) but after raiding a couple of hours with them, I only rarely seemed to get my procs up in time for AT, so I decided to do some testing with them:
From my tests it looks like these trinkets can only, in contrast to some of our other procs, proc on direct damage and dot applications. This means it can't proc on dot ticks (including NT cleave ticks) or cloak procs.
Since I am running with 2 ICD trinkets at the moment (BoI and cleave), this is quite devastating for my AT usage. Normally I get 4 AB's and one dot application off before I would want to AT normally - aka a grand total of 5 proc chances.
*please correct my maths if it is flawed*
Given 5 proc chances, 1 trinket and a proc chance of 15%, I have a 1 - 0.85^5 = ~55.6% chance of getting one proc.
Given 5 proc chances, 2 trinkets and a proc chance of 15%, I have a 1 - 0.85^10 = ~80.3% chance of getting one proc.
Given 5 proc chances, 2 trinkets and a proc chance of 15%, I have a (1 - 0.85^5)^2 = ~30.1% chance of getting both procs.
If I do another attack before at (dot application for instance), the chance rises to 38.8%,
2 extra attacks and I land on 46.2%
3 extra attacks and I finally go above 50-50 and land on 52.9%
This kind of RNG is simply not acceptable if you wanna be stable in a raiding environment.
**** ICD trinkets. At LEAST make them proc on dots like our meta/jadespirit/even lightweave (this would give us 10+ proc chances before AT).
This is going to be a huge stress factor during progression pulls - "Should I cast an extra spell or two, risking having my meta/other procs run out in order to get a little bigger chance of having the trinket proc before AT?? Should I AT without the procs and hope to god that they don't proc during AT?? Should I cancel AT if my trinket procs during??". IF you waste a proc, it's very mentally punishing in the sense that with RPPM, they could proc again any time - here you have to wait 85 or 115 seconds to get another chance!
I guess the bottomline must be that I'm looking very much forward to replacing my cleave trinket with an RPPM one, although I'll still be down at ~55.6% chance for BoI to proc before AT.
EDIT: On a lighter note, WHEN the stars align and I have all procs up, it's like being in heaven. Just did an ABarr crit for 1350k on a dummy. With flask, stat buff, mastery buff and crit banner that would easily go above 2m! Holy moley
